Membrane protection during storage
If the unit will not be in use for more than 7 days, the membrane must be protected according to the
storage instructions, see chapter „7.2.4 Membrane protection."
If the membrane is not regularly flushed or protected with the UNGER membrane care agent, there is a
risk of blockage and thus a strong performance limitation or damage.
Frost protection
Never store the HydroPower RO below 5°C. When not in use for a longer period of time, drain the water
from the HydroPower RO. Open the pressure relief valve on the back of the HydroPower RO until no water
leaks out.

Maintenance and maintenance plan
The HydroPower RO has its own monitoring system and informs the user about the operating state and
performance of the 4 filters by means of the display. It also warns of problems or status of each filter.
7.2.1
Daily inspection
Observe the indications on the display and the light signals on the 4 selection buttons next to the display
and if necessary, follow the instructions being shown by the system.
• Green = Everything is all right.
• Yellow = The values come within a critical range, provide a replacement filter.
• Red = Caution, you should now change the filter.
• Red flashing of the selection buttons = Warning, change this filter right now. The filter is no longer
effective and will cause the other filters to be used excessively, and the cleaning performance is no
longer guaranteed.
7.2.2
Quarterly examination
• Grease the o-rings in each of the four top caps with a non-silicone-based grease.
• Lubricate the water connections with lubricant or oil, such as WD 40.
7.2.3
Extraordinary maintenance
The software of the HydroPower RO can be updated. You can download the latest version from the Unger
website.
Save the file to a USB flash drive. The exact update process can be found in chapter „5.8 Software update".
